[Elecraft] K3 Attenuation on Receive of 20 meter band only problem.

[Phil Hystad]

Rick,

I just now discovered the RX antenna on.  I mean, Just seconds before your message came in.  But, thanks for the quick response and the correct answer.

There are so many features on the K3, sometimes finding the problem is more time-consuming.

thanks,
73, phil, K7PEH

I thought the band was dead this morning which seems unusual since this is a big SSB DX contest.  My other bands are busy as you would expect and I have made a number of DX contacts on 15 and 10 meters this weekend.
